Spinach

Patrick O’Donnell Science B2 Question: How does the presence of light affect the production and consumption of carbon dioxide in plants? The initial energy that lights gives to the chloroplasts ultimately affect the amount of carbon dioxide that is consumed and produced. To start the light dependent stage of photosynthesis, sunlight is needed for the initial energy in which the chlorophyll in the chloroplast harnesses. Water is taken in by the xylem tissues in the roots. The water molecules…

headache, brittle nails. In order to treat iron deficiency anemia, it is necessary to normalize the level of iron in the blood. An important role in achieving a normal level of iron, has adequate nutrition. So find out which foods are rich in iron. Spinach Spinach is one of the richest natural sources of iron. Besides iron, this plant is rich in vitamin A and E, calcium,…

Identifying the Photosynthetic Pigments Introduction: This experiment was mostly introduced as identifying the different photosynthetic pigments between the Spinach and Blue-green algae. These two pigments were well used in this experiment and simply finding the appearances. Our group was to experiment both these pigments by the amount of bands there was to use, the distance between one band to another, the band color, the distance pigment migrated from the distance solvent front migrated,…

floating and from 0:30 to 2:30, only one disc was floating. In a pH 4 solution, no discs were floating in any of the time intervals. It was concluded that photosynthesis of spinach leaves was at its highest rate at in a pH solution between six and ten, with pH 6 causing the highest rate. Therefore, the rate of photosynthesis for the spinach leaves is at its highest when in an environment that isn’t too acidic and is around a neutral, or somewhat basic, environment. Some percentage errors of this…

I want to be able to understand my current diet before any moderations. For breakfast on Tuesday, January 30th, I had whole grain cereal with almond milk as well as a cup of coffee with cream and sugar. I had a spinach salad for lunch with vegetables, cheese, and balsamic dressing. For dinner, I made flatbread pizza with mozzarella cheese, tomatoes, and mushrooms. I mostly drank water and a glass of iced green tea for lunch. After analyzing my diet on this day and…

It's not where you start, it's where you finish. So get the morning off to a great start with a bowl of high fiber cereal with fresh fruit. Fiberlady is pleased to inform you that if you choose a cereal high in fiber with your favorite fruit topping, you could get as much as a third of your daily fiber requirement. For optimal health, 25-30 daily grams of fiber-rich foods is the goal. High fiber foods effectively reduce the risk of cancer, gastrointestinal conditions and diseases, and the all…

make photosynthesis and its reactions more effective Experiment #2 Action Spectrum: Floating Spinach Disk Hypothesis: There will be more floating spinach disks in blue, red, and white light than in dark or green light because photosynthesis tends to be more effective when exposed to blue, red, and white light wavelengths. Null Hypothesis: There will be no difference in the number of floating spinach disks when exposed to blue, white, red, and green light, along with absence of light.…

The purpose of this experiment was to determine the correlation of light intensity and wavelength on white light, no light, red light and green light color treatments when looking at spinach. The same spinach plant was tested under different light environments (no light, white light, red light and green light). A control cuvette was used to compare the rate of photosynthesis to those of the color transmittance cuvette. Before collecting the data we learned about plants and light absorption. We…

EXPERIMENT #2 – ACTION SPECTRUM: FLOATING SPINACH DISK: Hypothesis: I hypothesized that the colored light will produce the most photosynthetic activity due to the larger wavelenth Null Hypothesis: For my null hypothesis I stated that there would be no effect of different colored light on photosynthetic…

Brooklyn Venturella Anthropology 2281, Schaefer Reconstructing Behavior October 18, 2015 Reconstructing Behavior To determine activity patterns from skeletal remains, the eye sockets are very important to view. Oversized eye sockets show that a primate is nocturnal, as sockets are much smaller on primates that are diurnal. Post orbital bars are also linked to nocturnal primates, whereas a post orbital plate is linked to diurnal primates. The post orbital bar creates a space behind the eyes. The…
